______________________________________________________________________________

1) problem description, brief discussion

    This update fixes several security issues in the ImageMagick program suite:
    
    - A format string vulnerability was found in the display program
      which could lead to a remote attacker being to able to execute code
      as the user running display by providing handcrafted filenames of
      images. This is tracked by the Mitre CVE ID CAN-2005-0397.

    Andrei Nigmatulin reported 4 problems in older versions of ImageMagick:
    
    - A bug was found in the way ImageMagick handles TIFF tags.
      It is possible that a TIFF image file with an invalid tag could
      cause ImageMagick to crash.
      This is tracked by the Mitre CVE ID CAN-2005-0759.

      Only ImageMagick version before version 6 are affected.

    - A bug was found in ImageMagick's TIFF decoder.
      It is possible that a specially crafted TIFF image file could
      cause ImageMagick to crash.
      This is tracked by the Mitre CVE ID CAN-2005-0760.

      Only ImageMagick version before version 6 are affected.

    - A bug was found in the way ImageMagick parses PSD files.
      It is possible that a specially crafted PSD file could cause
      ImageMagick to crash.
      This is tracked by the Mitre CVE ID CAN-2005-0761.

      Only ImageMagick version before version 6.1.8 are affected.

    - A heap overflow bug was found in ImageMagick's SGI parser.
      It is possible that an attacker could execute arbitrary code
      by tricking a user into opening a specially crafted SGI image
      file.
      This is tracked by the Mitre CVE ID CAN-2005-0762.

      Only ImageMagick version before version 6 are affected.

2) solution/workaround

    Please install the updated packages.

3) special instructions and notes

    None.

4) package location and checksums

    Please download the update package for your distribution and verify its
    integrity by the methods listed in section 3) of this announcement.
    Then, install the package using the command "rpm -Fhv file.rpm" to apply
    the update.
    Our maintenance customers are being notified individually. The packages
    are being offered to install from the maintenance web.

    See SUSE Security Summary Report.

______________________________________________________________________________

6)  standard appendix: authenticity verification, additional information

  - Package authenticity verification:

    SUSE update packages are available on many mirror ftp servers all over
    the world. While this service is being considered valuable and important
    to the free and open source software community, many users wish to be
    sure about the origin of the package and its content before installing
    the package. There are two verification methods that can be used
    independently from each other to prove the authenticity of a downloaded
    file or rpm package:
    1) md5sums as provided in the (cryptographically signed) announcement.
    2) using the internal gpg signatures of the rpm package.

    1) execute the command
        md5sum 
       after you downloaded the file from a SUSE ftp server or its mirrors.
       Then, compare the resulting md5sum with the one that is listed in the
       announcement. Since the announcement containing the checksums is
       cryptographically signed (usually using the key security@suse.de),
       the checksums show proof of the authenticity of the package.
       We disrecommend to subscribe to security lists which cause the
       email message containing the announcement to be modified so that
       the signature does not match after transport through the mailing
       list software.
       Downsides: You must be able to verify the authenticity of the
       announcement in the first place. If RPM packages are being rebuilt
       and a new version of a package is published on the ftp server, all
       md5 sums for the files are useless.

    2) rpm package signatures provide an easy way to verify the authenticity
       of an rpm package. Use the command
        rpm -v --checksig 
       to verify the signature of the package, where  is the
       filename of the rpm package that you have downloaded. Of course,
       package authenticity verification can only target an un-installed rpm
       package file.
       Prerequisites:
        a) gpg is installed
        b) The package is signed using a certain key. The public part of this
           key must be installed by the gpg program in the directory
           ~/.gnupg/ under the user's home directory who performs the
           signature verification (usually root). You can import the key
           that is used by SUSE in rpm packages for SUSE Linux by saving
           this announcement to a file ("announcement.txt") and
           running the command (do "su -" to be root):
            gpg --batch; gpg < announcement.txt | gpg --import
           SUSE Linux distributions version 7.1 and thereafter install the
           key "build@suse.de" upon installation or upgrade, provided that
           the package gpg is installed. The file containing the public key
           is placed at the top-level directory of the first CD (pubring.gpg)
           and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de .


  - SUSE runs two security mailing lists to which any interested party may
    subscribe:

    suse-security@suse.com
        -   general/linux/SUSE security discussion.
            All SUSE security announcements are sent to this list.
            To subscribe, send an email to
                .

    suse-security-announce@suse.com
        -   SUSE's announce-only mailing list.
            Only SUSE's security announcements are sent to this list.
            To subscribe, send an email to
                .

    For general information or the frequently asked questions (faq) 
    send mail to:
         or
         respectively.
